Paeonicluside, a new salicylic glycoside from the greek endemic species Paeonia clusii

Abstract

A new glycoside of salicylic aldehyde, paeonicluside, was isolated from the roots of the Greek endemic species Paeonia clusii subsp. clusii and identified as α-L-arabinopyranosyl-(1→6)-O-β-D-glucopyranoside of salicylic aldehyde (1). In addition, one characteristic monoterpene and two monoterpene glycosides were identified as paeoniflorigenone, paeoniflorin and benzoyl paeoniflorin, respectively. The structure of 1 was elucidated on the basis of its spectroscopic data and chemical correlation. It is the first time that a derivative of salicylic aldehyde is isolated from the well-studied Paeonia genus.
